Description

Technical Field

[0001] This application relates to the technical field of antennas, and more specifically, to an antenna integration device and underwater equipment. Background Technology

[0002] Underwater equipment (such as underwater robots) uses antenna integration devices for its communication equipment. Antenna integration devices refer to devices that integrate communication modules with antenna devices.

[0003] The inventors of this application have discovered that underwater equipment relying solely on satellite communication faces the risk of signal obstruction and communication interruption, while relying solely on radio communication carries the risk of communication interruption due to exceeding the effective signal coverage range or obstruction by obstacles. The bent RF cables used in existing antenna integration devices increase the RF path length and insertion loss. Furthermore, existing antenna integration devices are often complex in shape and occupy a large volume, which can increase drag if used in underwater robots.

[0004] The content in the background section is merely technology known to the public and does not necessarily represent existing technology in this field. Utility Model Content

Figure 1 A schematic diagram of the appearance of an antenna integration device according to an embodiment of this application is shown. Figure 2 This illustration shows another external schematic diagram of the antenna integration device according to an embodiment of this application. Figure 3 A schematic cross-sectional view of an antenna integration device according to an embodiment of this application is shown. According to an example embodiment, such as... Figure 1 , Figure 2 and Figure 3 As shown, the antenna integration device 1 includes a first housing 11, a communication module 12, a second housing 13, a connector 14, and an antenna assembly 15. The first housing 11 has a first receiving cavity 111 inside. The communication module 12 is disposed in the first receiving cavity 111. The second housing 13 has a second receiving cavity 131 inside. The connector 14 houses a connecting cable 141, with one end connected to the first housing 11 and the other end connected to the second housing 13. The connector 14, the first housing 11, and the second housing 13 are coaxially arranged in the horizontal direction.

[0027] For example, the connecting cable 141 is an radio frequency connecting cable. For example, the connector 14, the first housing 11, and the second housing 13 are all cylinders.

[0028] Antenna assembly 15 includes a first satellite communication antenna 151, a second satellite communication antenna 152, and a radio antenna 153. The first satellite communication antenna 151 is disposed in the second accommodating cavity 131 and connected to the communication module 12 via a connecting cable 141. The second satellite communication antenna 152 is disposed in the second accommodating cavity 131 and connected to the communication module 12 via a connecting cable 141. The radio antenna 153 is disposed in the second accommodating cavity 131 and connected to the communication module 12 via a connecting cable 141. The first satellite communication antenna 151, the second satellite communication antenna 152, and the radio antenna 153 are coaxially arranged in the horizontal direction.

[0029] Through the above embodiments, this application achieves a compact layout of a multi-antenna system by integrating the first satellite communication antenna, the second satellite communication antenna, and the radio antenna and coaxially arranging them horizontally within the second accommodating cavity of the second housing, and connecting them to the communication module of the first housing via connecting cables within the connector. This reduces the size and complexity of the device. Furthermore, the horizontally coaxial connector, the first housing, and the second housing prevent bending of the RF cables, thereby reducing RF loss and improving the stability of signal transmission.

[0030] According to the example embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the second shell 13 has a club-shaped structure.

[0031] Through the above embodiments, by defining the second housing as a club-shaped structure, this application can utilize the streamlined curve characteristics of the club-shaped structure to reduce the fluid resistance of the antenna integration device when used underwater.

[0032] According to the example embodiment, the first satellite communication antenna 151 is a Tiantong antenna and the second satellite communication antenna 152 is a Beidou antenna.

[0033] Through the above embodiments, this application improves the system robustness of the antenna integration device in complex underwater environments by defining the first satellite communication antenna and the second satellite communication antenna.

[0034] According to the example embodiment, such as Figure 1 , Figure 2 and Figure 3As shown, the communication module 12 includes a first satellite communication module 121, a second satellite communication module 122, and a radio communication module 123. The first satellite communication module 121 is connected to the first satellite communication antenna 151 via a Tiantong radio frequency cable (not shown) in the connecting cable 141. The second satellite communication module 122 is connected to the second satellite communication antenna 152 via a Beidou radio frequency cable (not shown) in the connecting cable 141. The radio communication module 123 is connected to the radio antenna 153 via a radio frequency cable (not shown) in the connecting cable 141.

[0035] Through the above embodiments, this application reduces signal crosstalk by connecting the first satellite communication module, the second satellite communication module, and the radio communication module to their respective antennas via corresponding RF cables. Furthermore, the coaxial layout shortens the RF path, reduces bending losses, and improves signal transmission efficiency.

[0036] According to the example embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the first housing 11 is provided with an external threaded interface 112, which is used for detachable connection with underwater equipment (such as an underwater robot).

[0038] According to the example embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the external threaded interface 112 is provided with a sealing gasket (not shown in the figure) and a waterproof and breathable valve 1121.

[0039] Through the above embodiments, this application improves the sealing performance of the external thread interface when connected to underwater equipment (such as an underwater robot) by setting a sealing gasket and a waterproof and breathable valve at the external thread interface, and avoids leakage of the first housing due to pressure changes.

[0040] According to the example embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the connector 14 is a straight rod structure, and its two ends are detachably connected to the first housing 11 and the second housing 13 respectively through metal threaded interfaces (not shown in the figure).

[0041] Through the above embodiments, this application improves assembly and disassembly efficiency by providing metal threaded interfaces at both ends of the straight rod-shaped connector, enabling rapid assembly and disassembly of the first and second housings. Furthermore, the threaded connection allows for partial replacement of damaged components (such as replacing the connecting rod or housing) without requiring overall disassembly, thus reducing maintenance costs.

[0042] According to the example embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the cross-sections perpendicular to the axial direction of the first housing 11, the connector 14, and the second housing 13 are all circular. The diameter of the first housing is 80-90 mm and the length is 140-150 mm, the diameter of the connector is 15-20 mm and the length is 500-530 mm, and the diameter of the second housing is 30-40 mm and the length is 350-420 mm.

[0043] For example, the first housing 11 has a diameter of 85.5 mm and a length of 144.73 mm, the connector 14 has a diameter of 18 mm and a length of 526.5 mm, and the second housing 13 has a diameter of 35 mm and a length of 400.4 mm.

[0044] Through the above embodiments, this application reduces the overall size of the antenna integration device and improves its portability by setting the specific dimensions of the first housing, the connector, and the second housing.

[0045] According to the example embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the inner wall of the first housing 11 is provided with a shock-absorbing pad (not shown in the figure).

[0046] Through the above embodiments, this application reduces the vibration and impact on the communication module disposed inside the first accommodating cavity by providing a shock-absorbing pad inside the first housing, thereby improving the stability of the antenna integration device.

[0047] According to the example embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the first housing 11 is provided with a watertight connector 113, which is used for detachable connection with underwater equipment (such as an underwater robot).

[0048] Through the above embodiments, this application improves the sealing performance of the connection between the antenna integration device and the underwater equipment by providing a watertight connector in the first housing to connect the underwater equipment (such as an underwater robot).

[0049] According to another aspect of this application, an underwater device is also provided, including the antenna integration device described above.
